6、F)inorder to simulate service aging.This method utilizes theGardner straight-line washability apparatus as a means forcontrolled removal of the dried films.A heavily weighted padis employed as a means of arriving at a scrubbing force similarto that of hand scrubbing.In order to distinguish between t
7、herelative removal properties of different polishes,the number ofoscillations required for complete removal is taken as ameasure of removability.4.Significance and Use4.1 This test method is used to predict removability of floorpolish after a treatment period that simulates aging in the field.It all
